F48-70型水下防喷器组研制

摘要

结合目标平台,采用防喷器结构优化技术、胶芯超弹性复合体三维仿真模拟分析技术、高强度高韧性低合金钢制造技术、抗硫剪切闸板设计制造技术、耐高温胶料配方及硫化技术等水下防喷器组关键技术,研制出了国内首套F48-70型水下防喷器组.F48-70型水下防喷器组配置了抗硫剪切闸板、耐温177℃管子闸板、耐温149℃变径闸板,可满足高温高压、高含硫井钻井作业要求.该防喷器组通过了中国船级社、挪威船级社、四川科特石油工业井控质量安全监督测评中心等第三方的检验,检验结果符合API Spec 16A要求,为该水下防喷器在海上应用奠定了基础.%To combine with the target platform,the first domestic F48-70 subsea BOP stack were developed by using the key technology of subsea BOP that such as BOP structure optimization technology ,three dimensional simulation and analysis of the super elastic complex of rubber pack-ing unit,high strength and high toughness of low alloy steel making technology,anti sulfur shear ram design and manufacturing technology,high temperature resistant rubber formula and vulcani-zation technology,etc.The BOP stack configuration resisting H2 S shear ram,177 ℃ temperature pipe ram,149 ℃ temperature variable bore ram,which can meet the high temperature,high pres-sure,high content of H2 S well drilling.The BOP stack passed third inspection of CCS,DNV and Sichuan Kete Petroleum Well-control Quality Inspection Center.Test results meet the require-ment of API Spec 16A which lay offshore application foundation for the subsea BOP.
